Rainbow Dace Fish Has White Bubbles On Its Head

[Zebrazebrazebra]

Not sure what is wrong a my fish behavior is normal, but he recently developed these small bubbles on his head. Anyone know what this is, if I need to treat? I've had no success getting new fish to survive in my tank besides the Dace and a goldfish. Any insights appreciated!

Any chance you can get a picture of the affected fish?

Could be a parasite called "Dermosporidia" usually a bubble forms then a little white worm will grow within it.
